Inventor: RAHN RALF-THOMAS
IPC: C07D315/00
Filed: 1999-04-21
Abstract: The invention relates to a method for producing 1,4-butanediol, tetrahydrofuran and .gamma.-butyrolactone by oxidation of butane to a product flow containing maleic anhydride, absorption of maleic anhydride from the product flow with a high-boiling alcohol, which yields a liquid absorption product containing maleic acid half- and diesters and high-boiling alcohol, post-esterification of the liquid absorption product and subsequent hydrogenation of the post-esterified product in the liquid phase. The high-boiling alcohol is a polyvalent alcohol with a boiling point at normal pressure of more than 233 °C and the post-esterified product has an acid value of less than 30 mg KOH/g and a water content of less than 1 weight %.

Patent CA-2333391-A1 (CA)
Inventor: JENNISSEN HERBERT PETER
IPC: G01N21/43
Filed: 1999-05-25
Abstract: The adsorption speed of proteins from solutions on surfaces in the area of boundary layers is frequently so high that a depletion of the proteins resul ts in the boundary layer. As a result, the entire reaction is transfer-dependen t thus substantially disrupting the determination of the speed constants. Up t o know, it has not been possible to remove these limitations with regard to transfer in preart total internal reflection fluorescence (TIRF) analysis chambers or biosensor systems having a liquid boundary layer of 10 .mu.m thi ck and mass transfer coefficients of 10-6-10-5 m/s. An ultra thin liquid layer results on the surface having a thickness of 100-200 nm, whereby boundary layers having a thickness of less than 100 nm are also technically possible,  with the aid of a TIRF flow-through shear analyzer in which a determined uni t of volume of a fluid which cannot be mixed, for example an air bubble, is fe d to the buffer current. The novel TIRF flow-through shear analyzer thus permi ts the generation of ultra thin liquid layers while increasing the mass transfe r coefficients for proteins by 50 to 100 times such that the sorption speed constants can be determined without limitations with regard to transfer.</SD OAB>

Abstract: In a cellular telecommunications system in which a geographic area is divide d into a hierarchical cell structure such that geographically small but high bandwidth-available cells are located in geographically larger cells of less  bandwidth-availability, mobile station connections are made based on the bandwidth requirements of the mobile stations together with the likelihood o f mobility of the mobile station within the cell structure. For mobile station s that have low bandwidth requirements and are highly mobile (such as telephones) the mobile stations are connected to cells at a cell layer havin g relatively large geographical areas yet low bandwidth-availability. On the other hand, for mobile stations with high bandwidth requirements, the mobile  stations are connected to geographically small cells with high bandwidth- availability. In this way, mobile stations with high bandwidth requirements yet low mobility can obtain the high bandwidths needed for their communications, while mobile stations with lower bandwidth requirements yet high mobility can move through the cell arrangement while minimizing the number of required handoffs.
Patent CA-2348723-A1 (CA)
Title: A wireless communication system using surface acoustic wave (saw) second harmonic techniques
Inventor: EDMONSON PETER J
IPC: H03H9/00
Filed: 2001-05-25
Abstract: SAW devices such as interdigital transducers (IDTs) have been widely used in RADAR applications and as filters. An IDT produces a SAW when excited by a single electrical pulse and can be fabricated to embody a code, which code provides for a passive autocorrelation of a SAW input to the IDT and thereby lends itself to further application as a signal generator in a communication device. However, internal dimensions of IDTs are inversely proportional to operating frequency, such that high frequency IDTs present significant manufacturing difficulties. Fabrication of IDTs for high frequency applications is simplified by exploiting a harmonic frequency SAW generated by IDTs. An IDT may therefore be designed according to fundamental frequency internal dimension criteria but can operate at a multiple of the fundamental frequency, thereby providing much higher frequency operation than conventional SAW systems. A communication system based on SAW harmonic techniques would be low-cost, low-power, small and simple alternative to known short range communications schemes, including for example the Bluetooth TM solution. Operation of a second harmonic SAW system at 2.4 GHz based on a fundamental frequency of 1.2 GHz is contemplated.

Title: The burst ratio: a measure of bursty loss on packet based networks
Inventor: MCGOWAN JAMES WILLIAM
IPC: H04L12/56
Filed: 2002-01-15
Abstract: A "Burst Ratio" is defined for use as a measure of the burstiness of a packet- based network. One illustrative implementation of the Burst Ratio (R) is where R is equal to the ratio of the average length of observed bursts in a packet arrival sequence over the average length of bursts expected for a random loss packet-based network. Another illustrative implementation of the Burst Ratio (R) is in the context of a 2-state Markov model, wherein R = 1 / (1 + .alpha. - .beta.), and .alpha. is the probability of losing packet n if packet n-1 was found (i.e., the probability of being the next packet if the current packet was received) and .beta. represents the probability of losing packet n if packet n-1 was lost (i.e., the probability of being the next packet if the current packet was lost).
